I claim:-

1. In the method for the cinematographic projection and thesubstantially vertical viewing of panoramic pictures taken verticallyfrom aircraft, wherein the pictures are projected vertically downwardupon a screen horizontally disposed below the level of the picturesthereon, the positions 01 the spectators in successively superposed anddiametrically decreased single rows surrounding and racing the verticalaxis of the screen.

2. In the combination or a cinematographic projector having facilitiesfor projecting panoramic pictures substantially vertically downward anda substantially horizontal screen upon which the pictures may beprojected and also seating means for spectators, the feature ofproviding said seating means in successive superposed and increasinglysmaller rows disposed above the screen and at least partiallysurrounding the vertical axis of the screen so that each spectator facessaid axis, and thereby providing for each spectator an unobstructeddownward vertical view of the projected pictures upon said screen.
